However, if the dating of pulsars is wrong, as has recently been suggested, then the Vela Pulsar could be much younger, and may have arisen only 4,500 years ago, or about the time of the Flood. The Vela supernova remnant is now about 230 light years across and covers over 100 times the sky area of the full moon.
I believe the Vela pulsar is still the largest source of gamma radiation in the night sky.  It’s a “smoking gun.”  Jueneman was the first to suggest a link between this pulsar and an acceleration of decay (Industrial Research, about 1972).
